Gibberish is meaningless talk or statements. The word is derived from 'gibber', to speak inarticulately or insanely. It's used in a purely derogatory sense as a descriptor, often dismissively, referring to the speech or ideas of another party.

Gibberish is also often used in humor, creating a characterization or caricature of an idea.
